Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering device provided downstream of a reel for supplying a material to a straightening machine, a molding machine, a squeezing machine, etc.・
Regarding the enlargement unit. The stretching unit of the present invention is installed downstream of a reel holding two or more wire rods or rolls of profile for metal reinforcement of concrete for construction work.

These rolls are suitable for feeding material to machines for straightening, shaping and drawing concrete reinforced slap for construction work on demand. The reel is located upstream of a straightening and forming machine suitable for producing reinforcing stalaps for construction work with closed or open shapes and various dimensions, which stalaps have reinforcing rods with different cross sections or Made from mold material. The reel holds two or more wire rods or rolls of mold material having different cross-sectional shapes.

A roll suitable for the desired shape of the stab is selected and the end of the wire rod or profile is set and straightened in a straightener. The end of each roll on the reel is positioned by projecting a segment (usually straightened by hand) from the rewind station. If the old wire rod or profile needs to be replaced, the old profile is used up or rewound into a roll and the protruding segment of the new profile is engaged with a gripper or manually inserted into the straightener.

These operations are very easy when the cross-sectional area of the mold material to be handled is small. However, recently, a problem arises in the case of a thick reinforcing steel mold member having a cross section of 12 mm in diameter, and in particular, it takes a lot of time and energy to process a mold member having a diameter of 16 mm or more. It requires consumption.

Since the wire rod and the profile material unwound from the roll are oriented in all three-dimensional directions, it is possible to mount the profile material on the machine while keeping it facing and to mount it in a direction in which it is easy to move. It should be noted that it is necessary. Accordingly, Applicants have investigated this particular problem and considered various solutions to complete the present invention.

The invention consists of what is stated in the characterizing part of claim 1, and the dependent claims describe various embodiments. According to the invention, the centering and stretching unit is installed between the reel and the processing machine and acts on the axis of the reinforcing wire rod or profile. The processing machine is preferably a straightening machine, a straightening / molding machine or a molding machine,
These machines are for producing concrete reinforcing elements or reinforced wraps for construction work.

According to the invention, the centering and stretching unit has an activated position and an inactivated position. The unit comprises an arm, which in movement from the inoperative position to the operative position engages a wire rod or profile supplied from the reel and brings it into the operative position. According to the invention, at least two paired rollers are provided,
One of them is configured to be driven. Each of these two rollers extends in the vertical direction at a predetermined angle on the front surface of each roller.
It has a book arm. These two arms of one roller are in substantial contrast to that of the other roller.

[0008] These rollers are relatively displaceable so as to occupy the operating position when working in cooperation with each other, and conversely move to the inoperative position when they are separated from each other. This relative displacement may be linear or curvilinear, and is preferably circular. This movement consists of substantially horizontal, vertical movements or a combination thereof. The invention is explained in more detail below on the basis of two exemplary embodiments in which a substantially horizontal movement is shown in the drawings.

[0009]

[Example] In the drawings, a centering / stretching unit 1
0 comprises two pairs of rollers 11, 12, which in this example have a V-shaped groove on the outer peripheral surface.
2 has an outer peripheral surface having a shape corresponding to the V-shaped groove. Each roller 11, 12 comprises an arm 13 projecting from each roller and arranged at a predetermined angle with respect to each other. One of these rollers (roller 11 in this example) is driven by a motor 14.

The rollers 11, 12 are mounted on a support arm 15 or a trolley 16. One or more actuators 17 are provided for moving the rollers 11, 12 to move them from the inoperative position 18 to the operating position 19. At the time of this displacement, the engagement arm 13 moves the mold member 20.
And move it to the cooperation position of the rollers 11 and 12.

In the operating position 19, the rollers 11, 12
Hold the mold members 20 against each other elastically. Instead of the two rollers 11 and 12, a set of more rollers may be used. FIG. 2 shows an example in which the trolley 16 can be rotated by 90 °, and the trolleys 16 are oriented so that their vertices are directly above (not shown) in order to save space in the entire lateral direction, and the trolleys 16 are set at predetermined angles with respect to each other. It is possible to run on guides that are arranged.
